WATER-BACK FOR GAS-STOVES.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed February 14,1914. Serial No. 818.763.

To a whom it may concern:

Be itknown that I. ARTHUR Hnaoenn, a citizen of the United States, residing at Brooklyn, in the county of Kings and State .of New York, have invented certain new and useful Improvements in lVater-Backs for Gas-Stoves, of which the following a full, clear, and exact specification.

This invention relates to waterbacks or water heaters especially designed to be used on gas stoves for the purpose of heating water at the same time that the gas burner is being used for; cooking purposes.

The principal ob ect of the invention is to provide a waterback for gas stoves which will heat water in a minimum space oftime and without detracting materially from the heat supplied to a cooking vessel placed over the burner in the usual 'way.

Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of this specification, and then more specifically defined in the claims at the end of the descrip tion. T I

In the accompanying drawings, wherein similar reference characters are used throughout the several views to designate corresponding parts :-Figure 1 is a 'vertical sectional view of a waterback constructed in accordance with my invention and plied to a gas burner, the latter being modified slightly in construction to adapt it to my purpose. Fig. 2 is a plan view of the assembled device shown in Fig. 1. Fig. 3

is a detailed plan view of the burner and Fig. 4 is an enlarged detail sectional view to illustrate how the flames from the burner play upon the bottom and the inner surfaces of the tubular passages in the waterback.

'Referring more particularly to the draw-- ings, A designates the waterback which may be generally fiat and circular in form and which is connected to a suitable receptacle for holding the hot water, as the tank B, by the circulating pipes b, b. The waterback may be further formed with a central and fwith a plurality of scattered gas pass/ages a, it being understood that the waterback as a whole is hollow, so that the water contained therein comes in intimate contact with the walls of purposes 1 wltich' would said gas passages as well the top and bottom thereof The gas burner C may be of the usual or any well known type having a plurality of gas emitting openings 0 in its upper surface. 00 The gas passages 11 in the waterback are arranged in vertical alinementwith certain of these gas emitting openings in the burner, preferably with alternate ones of said openings, as best illustrated in Figs. 1 and 3. The result is that the flames from some of the openings 6 in the burner will play upon the bottom of the waterback, while the flames from others of said openings will play into the passages a, in the waterback. In order to obtain the best results from these latter openings which are arranged in vertical alinement with the passages a in the water-back, extension tubes 0 are fitted in said openings, which tubes project well into the passages a, as clearly shown in Figs. 1 and 4. By this means, the flames from said tubes are carried through the passages a in the waterbaek and come in direct contact with the bottom D of a cooking vessel, Fig. at, without materially detracting from the heating power of the burner provided for cooking purposes. At the same time, these flames impinge upon the inner surfaces of from the openings 0 which are not equipped with extension tubes, laterally bv the flames playing in the passages a, and at the top by the heat thrown downward by the bottom of the cooking vessel. Accordingly, the water in said waterback must be heated in aminimum space of time. At the same. time the heatof said waterback itself will practically make up for any loss of heat for cooking otherwise result by reason of the fact that alternate jets of flame which play upon the bottom of the waterback do not. come in contact w""'h the bottom of the cooking vessel.

The burner may b provided with a contral air circulating passage 0 in vertical alinement with the passage (1 in the Waterback, see Figs. 1, 2 and 3. The form of burner shown has radiating arms a in which some of the gas emitting openings are formed. It will be understood, however, that any other suitable form or style of burner may be used, if desired, and provided with the extension tubes 0 in order to adapt it for the purposes of my present invention. Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:-

1. The combination, with a gas burner having gas emitting openings in its upper surface, of a waterback arranged over the burner and having passages thercthrough distributed over its horizontal extent, and tubular extensions fitted around some of the gas emitting openings in the burner and projecting into said passages in the Waterback, said passages constituting continuations of said tubular extensions to carry the flames from said extensions to the upper surface of the water-back, others of said gas emitting openings in the burner furnishing flames impinging on the lower surface of the waterback.

2. The combination, with a gas burner having gas emitting openings in its upper surface, of a Waterbaek arranged over the burner and having passages therethrough distributed over its horizontal extent in vertical alinement with alternate openings in the burner, and tubular extensions fitted around said alined openings and projecting into said passages in the Waterback, said passages constituting continuations of said tubular extensions to carry the flames from said extensions to the upper surface of the Waterback, the alternate n0n-alined openings in the burner furnishing flames impinging on the lower surface of the waterback. 3. The combination with a waterback having passages therethrough, of a gas burner having alternate ones of its gas emitting openings provided with tubular projections extending into said passages in the Wateroack.

4c- The combination with a Waterback having passages therethrough, of a gas burner having its gas emitting openings arranged in radial rows, alternate ones of said openings in each row being provided with tubular projections extending into the passages in the waterback.

5. The combination, with a gas burner havinggas emitting openings in its upper surface, of a fiat waterback to lie over said burner and below a vessel to be heated. said waterback having passages thcretl'n'ough in alincnient with some of 'the gas emitting openings of the burner, and tubular extensions from said alined openings projecting into said passages, the latter constituting co'ntinuations of said tubular extensions to carry the flames from said extensions to the upper surface of the watcrbaclr, others of said gas emitting openings in the burner furnishing flames to impinge on the lower surface of the water-back.

(S. The combination with a water-back hav ing an air circulating passage disposed centrally thereof and a plurality of gas circulating passages radially arranged, with respect to the air circulating passage, of a gas burner having a central air circulating opening in. alinement with the air circulating assa e in the Water-back and as emittin openings alternate ones of which are disposed in alinement with the gas circulating passages in the waterback.

7. The combination with a Waterback having; an air circulating passage disposed centrally thereof and a plurality of gas circulating passages radially arranged with respeet to the air circulating passage, of a gas burner having a central air circulating opening in alinement with the air circulating passage in the Waterback, and gas emitting openings, alternate ones of which are disposed in alinement with the gas circulating passages in the Waterback, and tubular projections from said alined openings extending into said gas circulating passages.

In testimony whereof I have signed my
